Cassia javanica subsp. agnes, commonly known as Agnes Shower or Pink and White Shower, is a deciduous tree native to the monsoon forests and lowland areas of Southeast Asia. It typically grows at a moderate rate to a height of 20-40 feet (6-12 meters) and a width of 20-30 feet (6-9 meters). The tree has a spreading canopy with compound leaves that provide dappled shade. During the summer, it produces clusters of fragrant, showy flowers that are pink or white, attracting pollinators and adding ornamental value to the landscape. The flowers are followed by long, slender seed pods.

Agnes Shower is valued for its striking floral display and is often used in tropical and subtropical gardens as a specimen tree or for shade. It is also suitable for urban planting due to its moderate size and tolerance of various soil types. This species requires full sun to thrive and prefers medium or fast-draining clay, loam, or sandy soils with regular watering to establish a deep root system. While it is generally low-maintenance, it can be susceptible to pests such as caterpillars and diseases like root rot in poorly drained soils. Gardeners should be cautious about planting Cassia javanica subsp. agnes outside its native range, as it has the potential to become invasive, outcompeting local flora and disrupting ecosystems.CC BY-SA 4.0
